MACHINERY FOR MOISTENING ROLLS OF PAPER.

SPECIFICATION forming part of Letters Patent No. 683,536, dated October 1, 1901.

Application filed October 9, 1900. Serial lilo. 32,541. (No model.)

To aZZ whom zit may concern.-

Be it known that I, JULIUS VVEZEL, a subject of the King of Saxony, residing at Leipsic, Kingdom of Saxony, Germany, have invented certain new and useful Machinery for Moistening Rolls of Paper, of which the following is a full, clear, and exact description.

The present invention relates to machinery for moistenin g rolls of paper for adhesive and calendering purposes; and it consists of the details of construction hereinafter set forth, and particularly pointed out in the claims.

In order to render the description easily intelligible, reference is had to the accompanying drawings, in which similar letters of reference denote similar parts throughout the several views.

Figure 1 is a side elevation of one form of machine embodying the invention, and Fig. 2 an end elevation ofthe same. Fig. 3 is a side elevation of a modified form of the machine, and Fig. 4 a similar elevation of a further modification.

The paper-rollogfrom which the paper passes to the moistening-roll a, is mounted to rotate in a carriage r adapted to move on suitable wheels in a direction transverse to that of the movement of the paper in order to enable the said roll to be adjusted properly as regards the moistening-roll a for paper of diiferent widths, so as to wind off paper of less width in a direction to bring the same to lie against one or other of the flanges of the roll a, as will be readily understood. The roll r, onto which the paper is wound after it has been moistened, is similarly mounted on a carriage r to enable its adjustment to receive the paper.

The moistening-roll a is mounted to rotate in a stationary frame a, carrying also a suitable number of distributing-rolls 1), running on the paper cl, passing over the roll a, and serving to distribute the water sprayed onto the said paper by the jets b. The jets b are mounted in suitable stands on a slide a, which may be adjusted toward and from the roll a on brackets a by means of guide-strips 0. These jets may be supplied with water by means of flexible pipe connections, (not shown,) as will be readily understood. The paper passes from the roll a over a series of guide-rolls w, mounted in suitable hearings on a carriage g, which runs in a direction toward and from the moistening-roll a by means of wheels g on rails g and may be adjusted in position on the latter. Between the rolls to any unevenness in the stretching of the paper passing over the said rolls may be compensated by means of rolls it, any suitable number of which may be employed. These rolls are loosely laid in the folds of the paper between the rolls w and serve to compensate any slackening of the same.

Below the rolls to a second series of guiderolls to is provided, also mounted in the carriage g. The upper ones of these rolls are carried in an arm 10 pivotally mounted in the carriage at to, and having its free end adjustable by means of a swinging screw-spindle 10 and hand-wheel 10 By this means the tension exercised by the rolls on the paper may be varied for different thicknesses of paper. The paper is then wound onto the roll 1" in the ordinary manner. The rolls a r r, as also any of the guide-rolls, may be driven in any of the well-known ways, which need not be described here.

The operation of the machine is as follows: It should be mentioned here that the object of the present arrangement of adjustable rolls is to render the machine in every respect adj ustable, so that paper of any desired thickness may be moistened on the same, it also being indifferent whether the capability of absorbing moisture of the various kinds of paper be great or small. If a thin paper is to be moistened, the carriage g is adjusted near to the moistening-roll a, so that the length of freely-hanging paper is reduced and the danger of the same breaking or tearing when moistened is obviated. Then, again, if a thin paper is being treated, the jets b must be re moved farther back from the roll a, which is done by adjusting the same farther back on their brackets a This has the effect that then onlya fine spray of water will reach the paper, the heavier drops falling short of the drum 0.. For thicker paper or for paper which will not readily absorb the moisture the car riage g is adjusted farther from the roll a,

while the jets I) should be advanced toward the same. According to the quality of the paper also the number and weight of the compensating rolls h should be chosen.

It will be readily understood from the above description that the ad justability of the parts in order to attain the required object might be carried out in a variety of ways. For instance, as indicated in Fig. 3, the rolls 'w and 10 need not be mounted on a single carriage g, but on a set of carriages is k 70 mounted to run on fixed rails it so that the tension may be varied by different adjustment of the carriages apart instead of by the adjustment of some of the rolls w by means of the screwspindle 10 In Fig. 4. a long stationary frame a is employed,having a series of bearings 'm, on, and m arranged on upper and lower rails 'n and n These bearings are stationary and carry the rolls w and w in three superposed rolls similarly to the other two embodiments. In this case a variation of the tension exercised on the papers of various kinds is attained by omitting a certain number of rolls for thin or absorbing paper and by passing the paper around all the rolls if it is of the tougher class.

If the space available for themachine is limited, the sets of rolls to and w may be mounted or arranged above the roll a, as will be readily understood.

I claim as my invention 1. In a machine for moistening paper comprising a moistening-roll, winding-01f and winding-up rolls and a series of tension and guide rolls the combination of a series of water-jets adjustable to and from the moistening-roll and sets of tension-rolls also adjustable toward the said moistening-roll in the manner substantially as described. 2. In a paper-moistening machine, the-combination of a moistenin g drum or roll and Water-jets adjustable to and from the same, a

winding-0E roll and a windingup roll for the paper, a carriage adjustable to and from the moistening-roll having a series of tensionrolls'thereon over which the paper passes before it is Wound onto the Winding-up roll substantially as described.

3. In a paper-moistening machine, the combination of a moistening-drum having a series of water-jets adjustable toward and from the same, winding up and winding-off rolls as specified, a carriage adjustable to and from the moistening-roll and having a series of tension-rolls arranged in superposed position and means for adjusting the same as regards each other in the manner and for the purpose substan tially as described.

4. In a moistening-machine the oombination of a moistening-roll having a series of jets adjustable toward and from the same, a winding-0E roll and a winding-u p roll and a series of tension-rolls arranged between the moistening-roll and the Winding-up roll and means for adjusting the amount of tension of the same substantially as described.

5. In a moistening-machine the combination of a moistening-roll having water-jets adjustable toward and from the same, a wind ing-oit and winding-up roll, a series of adjustable tension-rolls and means for compensating or taking up any slackness of the paper between the said rolls substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.

JULIUS IVEZEL.
